Besides cooperation, most interactions are governed by politeness, that is to say by what is considered a “polite social behaviour” within a certain culture.
The Politeness Principle is a series of maxims, which Geoffrey Leech has proposed as a way of explaining how politeness operates in conversational exchanges.
LEECH’S MAXIMS
Leech defines politeness as a type of behaviour that allows the participants to engage in a social interaction in an atmosphere of relative harmony. In stating his maxims Leech uses his own terms for two kinds of illocutionary acts. He calls representatives “assertives”, and calls directives “impositives”.
Each maxim is accompanied by a sub-maxim, which is of less importance. They all support the idea that negative politeness (avoidance of discord) is more important than positive politeness (seeking concord).
Not all of the maxims are equally important. For instance, tact influences what we say more powerfully than does generosity, while approbation is more important than modesty.
Speakers may adhere to more than one maxim of politeness at the same time. Often one maxim is on the forefront of the utterance, while a second maxim is implied.
FACE AND POLITENESS STRATEGIES
“Face” (as in “lose face”) refers to a speaker's sense of social identity. Any speech act may impose on this sense, and be therefore face threatening.
Speakers have strategies for lessening the threat.
Positive politeness means being complimentary and gracious to the addressee (but if this is overdone, the speaker may alienate the other party). Negative politeness is found in the various ways of mitigating an imposition.
Negative politeness can take the form of:
Hedging: Er, could you, er, perhaps, close the, um , window?
Pessimism: I don't suppose you could close the window, could you?
Indicating deference: Excuse me, sir, would you mind if I asked you to close the window?
